, 12 Claims. (e11. 105-80) This invention relates to improvements in railway vehicles and lateral -motion resistance de vices therefor, the resistance devices being in 'some respects similar to the resistance device shown in Patent No. 1,946,893, granted to m February 13, 1934. v

An object 'of the invention is to provide a resistance or cushioning device of the type aforementioned in combination with an axle and its associated parts for a railway vehicle, wherein the axle is permitted a limited lateral movement in opposite directions from normalposition, relative to the frame of the vehicle and the axle journal housings are constrained for lateral movements onlywith the axle in said opposite directions. i

A further object of the invention is to provide a construction having the above mentioned characteristics wherein frictionless bearings for 2o transmitting the load of the vehicle'fro'm the vehicle frame to the axle are interposed between the axle and housings and constrained for lateral movements, only with the axle and housings.

, A further object of the invention is to provide 25 constructions as aforementioned wherein the re sistance or cushioning device comprises lateral motion resistance means and at each end an end portion disposed at its outer end opposite its adjacent side frame member of, the vehicle frame,

30 and a part disposed inward from its outer end opposite an abutment of the adjacent housing whereby, when one of said abutments is moved in a direction toward the other abutment by force, as for instance a shock emanating from 5 the adjacent wheel flange when entering upon the outer track of a curved portion of track, the adjacent end portion of the resistance or cushioning device will be moved, by its adjacent abutment, correspondingly against the resistance of 0 the'lateral motionresistance means, and movement of the opposite end portion will'be stopped by its adjacent side frame member thereby af fectlng a cushioning of such shock. I A further object of the invention is to pro- 45 vide a lateral motion-resistance or cushioning de-'- vice of the aforementioned characteristics.

Further objects of and advantages achieved by this invention will be apparent from the following detailed description of approved embodiments of the invention which are illustrated in the accompanying drawings. J

In the accompanying drawings: Figure 1 is, at.

Referring now to Figs. 1 to 3, the construction here shown is directed more particularly to a driving axle l of a locomotive, although the form of the invention here illustrated is not so limited but may be employed with any axle of a railway vehicle and its associated parts where found appropriate. The frame 2 of the vehicle is illustrated only insofar as is necessary for a clear understanding of the invention. It comprises side frame members it and t disposed one at each side of the locomotive provided with pedestal jaws 5, binders t and. shoes I. One of 40 the shoes, as the shoe at the left, Fig. 3, serves as a wedge which willbe understood is" provided with the usual adjusting screw (not shown) Journal housings 8 and 9 are provided; each for a portion of the axle! at each side of the 1000- -motive, spring saddles l0 being supported on the top thereof. A housing It rigidly connects the two journal housings 8 and 9. This rigidity I of connection constitutes one.of the differences a in construction betweenthis embpdiment'of the invention and that exemplified in Figs. 4 to 6, as will later more fully appear.

While, broadly viewed, the lateral motion resistance or cushioning devices, their associated parts and their manner of functioning, later to be described, may be employed with axle con- In the construction of Figs. 1' a 3, now being particularly described, a frictionless hearing I! is disposed between the journal housing 8 and its adjacent axle portion. This bearing is in the main similar to the well-known type of Timken roller-bearing shown for'ifnstance in the United States patent to Buckwalter, No. 1,860,702, May 31, 1932,- which patent also shows a form of housing similar in principle to the housing I I, and for a fuller understanding of these features reference may be had to this patent.

The frictionless bearing 12 in the present instance comprises a ring-shaped inner race l3 snugly encircling the adjacent portion of the axle I, an outer race It snugly housed in the adjacent journal housing anda series of conical rollers l5 arranged in a circle within the usual cage (not shown) between the races. The rollers of the series tilt in outwardly converging direc- A bearing l2 similar to the bearing l2, the,

parts thereof bearing reference numerals similar to the corresponding parts of the, bearing I2 but 1 with accents added, is disposed between the jourwheels of the rial housing 9 and its adjacent axle portion, and a collar I1 and a filler ring l8, similar to the corresponding collar l1 and filler ring' l8, are provided. The race i4 is seated against a shoulder l9 provided in the housing 8 and the race I 4' is seated against a shoulder I! provided in the housing 9. r

Due to the construction of the parts as thus described, the housing ii, its adjacent bearing l2 and adjacent portion of the axle I provide an assemblage and the corresponding parts at theopposite end of the axle. provide a similar .to' the housing II which rigidly connects the assemblage, each of which assemblages moves bodily, and furthermore they move together, due

housings 8 and 9, when the axle I is moved laterally by a force, such as-is produced, when the axle are entering a curve, by. the flange of theouter wheel striking the flange of the outer rail.

To permit. these lateral movements bodily of .the assemblages the respective journal housings ftion, for such movement is required to effect the members 3 and 4 respectively. This provision for relative lateral movement between the assemblages and their respective side frame members forms an important part of the present invenoperations of the lateral motion resistance device of the present invention in order to prevent or minimize the shocks that would otherwise be transmitted from the wheel flanges to the frame of the vehicle which'would finally reach the superstructure through the connecting parts. This provision for relative lateral movement between the assemblages and their re pective side frame members is not only prese t in the construction of Figs. 1 to 3 but is equally present in the. construction of Figs. 4 to 6, as

will later more fully appear.

- housing. is provided with flanges 20 overlapping and spaced from the adjacent portions of their respective side frame members 3 and 4, and conveniently termed,frame flanges". More strictly speaking these flanges are spaced from the shoes I, but for. convenience theseshoes will be hereafter throughout the specifications and in the claims considered as constituting parts of their The frame flanges 2B in the present embodiment are formed respective side frame members.

integral with the flange members 2| which are separate from their respective housings 8 and ousings suitably I 9 but pivotally connected thereto by trunnions 25 22 projecting from the" end faces of the housings at the horizontal plane of the axle axis into orifices 23 provided in the members 2 I-. This permits the journal housings to tilt with the axle relative to the 'frame without disturbing the proper position of the flanges 20 relative to their respective side frame members, while at the same time insuring vertical movement of the flanges 20 with their respective housings.

Each of the housings is provided with an abutment at each side of the aide in the horizontal plane of the axis of the axle and opposite an adjacent flange 20 disposed at the inner side of its adjacent side frame membef. In the present instance the abutments are formed at the extreme ends of the housing H and comprise bifurcated lugs 24, which may be considered, for

convenience, as forming parts of the housing B,

The lateral motion resistance device ,of the present invention is in various respects similar in construction to the device shown in my- Patent 1Y0. 1,946,893, and reference may accordingly be had thereto for a more detailed description thereof. While such device is the preferred construction, it will be understood that the invention is not limited'to any particular flzype of device except insofar as itshould comprise the characteristics of the device of the present invention which differ from thedevices of the prior art.

For instance where, in the present instance, two

helical springs are employed, a single helical spring may be substituted or instead thereof any appropriate disc or leaf spring may be used.

Referring more particularly to the construction of the device of the present invention, two devices are employed, one at each side of the axle in the horizontal planepf the axis thereof. As the two devices are similar in all respects and similarly positioned, a description of one will suflice.

The device, indicated generally by the reference numeral 30, comprises end'portions 3| and 32 extending respectively through their adjacent clear ways provided by the adjacent passageways is providedwith a socket 31 at its inner end and a spacing bar 38 is housed at its opposite ends in these sockets. A slot 39 is formed through each end of the bar and a bolt 4|! is disposed in each slot with its ends secured in its respective end portion. This provides for limited relative lateral movements of the end portions and when the bolts 40 abut the outer ends of their respective slots the end portions are then at their extreme outward positions providing thereby a maximum length for the device between its outer end portions and a maximum distance between the respective shoulders.

' A collar M is loosely mounted on the bar 33 and a helical spring 42 is mounted on the bar at each side of the collar, having its inner end hearing against the collar and its outer end bearing against the inner face of its adjacent end portion. The springs are preferably under compression, thereby normally holding-the end portions in their outermost positions, the maximum length of the device being preferably such that the device fits freely between the side frame members and the portion between the shoulders fits freely between the lugs, with little or no play.

It will be noted that the frictionless bearings as thus described are so constructed that if it were not for the housing ii (and if no other means were substituted) the journal housings d and d and their respective adjacent outer races it and it would be free to move outward relative to the axle and the respective inner races iii and iii. With however the employment of the housing H as rigidly 'connected to the respective journal housings, no relative lateral movement of the parts forming the assemblages of axle portions, housings and frictionless bearings is permitted. The respective assemblages thus move laterally bodily. This movement bodily is essen- 'tial in constructions of the frictionless types of the present invention. The two assemblages are also forced to move together by the housing ii.

The outer ends of the end portions are preferably rounded in vertical planes by arcs 43 struck from the center 'of the device to provide suitable bearing surfaces when the axle moves vertically ortilts relative to the side frame members. And as these rounded surfaces are in the horizontal plane of the axle axis tilting of the axle may take place when thefiresistance means are resisting a wheel flange thrust without added and unbalanced resistance occurring. The bolts 26 closing the bifurcations of the lugs 24 provide a ready means for retaining the devices in place, and all that is necessary to remove a device from the vehicle when required and to assemble another device with the vehicle is to remove these bolts 26. The railway vehicle to which the present .invention is adapted is of the inside journal type and accordingly the axle I is provided at its upposite ends at the outer sides of the side frame members with wheels 44' and. 45, these in the present instance being shown as locomotive drive wheels.

The operation or this embodiment of the invention is as follows: When the axle moves vertically under servic conditions the entire journal assemblages, to-r gether with the housing II and the devices, move therewith bodily as a unit. And when the axle tilts, as when one ,wheel is passing over a higher section of track then the opposite wheel, the aforesaid parts tilt with it as a unit, with the exception of the flange members 2|, for, while these move vertically and laterally with the axle, they do not tilt therewith due to the pivotal connections between the members and their respective journal bearing housings. During these vertical and tilting movements there are corresponding movements of the outer ends of the end portions relative to the side frame members and the curvature given these ends, as aforementioned, permits suitable tilting to be effected, although under nor-' mal conditions there is preferably little or no pressure between these ends and their respective side frame members due to the construction of the devices, as aforedescribed.

When a shock is experienced producing or tending to produce a lateral movement of the axle relative to the side frame members, which movement is limited by the amount of space between the flanges 2b and their adjacent-side frame members, the devices function to cushion the shock in the following manner:

Consider a'shock due to the flange of the wheel ib striking'the rail flange of an outer rail when the wheel is entering upon a section of curved track. This shock would tend to move the race it with the axle toward the opposite frame member 3 away from the race it due to the direction of angularity of the bearing surface of the race M or, if the race it were loosely fitted to the axle, the axle could slide through the race iii, and the frictionless jbearing i2 thereby remain stationary when such a shock is transmitted to the axle. however do not occur due to the functioning of the housing ill, as will presently appear. They are here mentioned however because in these respects the frictionless bearing of the present construction (Timken bearing) varies materially from the frictionless bearing of the construction These possible relative movements shown in Figs. 4 to 6, the latter construction for is transmitted through the series of rollers H to the race i4, and from there to the housing 8, through the shoulder i9 formed thereon. This assemblage thus moves bodily with the axle i, and the housing ll being rigidly secured to the housing 8 moves therewith as does also the housing 9 which is likewise rigidly connected to the housing ii. The shoulder i9 formed on' the race i4 due to its engagement therewith. The

race i4, due to the direction of angularity of its bearing surface and that of the race 13', effects a similar movement of the series of roller bearings l5 and race l3. Thus both assemblages move simultaneously bodily in the same I direction under such a shock orblow.

. housing 9 produces a similar movement of .the

During this movement of the axle and its aforementioned associated partsghe abutment or lug 25 of the housing 3 bears -positely disposed part or shoulder 36 of the end portion 32 carrying this end portion with it, the outer end 34 of whichbeing accordingly incidently moved away from its adjacent side frame member 4. This mdvement of the end portion 32 is against the resistance produced by the lateral motion resistance device. are accordingly compressed and the outer end 33 ainst the op- The springs 42.

of the end portion 3| is simultaneously brought 4 into spring-pressed engagement with its adjaeent side frame member 3, thereby stopping any movement of the end portion 3| in the direction of movement of thqaxle, thus producing the desired cushioning of this shock or blow to minimize its undesirable effect upon the vehicle, the abutment or lug 24 being simultaneously incidently moved away from the adjacent part or shoulder 35 of the end portion 3|.

It will be-understood that both of the devices operate simultaneously in the same manner, and

also that the various parts function in a corresponding manner to effect a similar cushioning when the blow or sli ock emanates from the wheel 44. The parts adjacent the side frame member 3, during such shock or blow, function similarly to the parts adjacent the side frame member 4, and. vice versa, as just described when the blow orshock emanated from the wheel 45, and a more detailed description is not deemed necessary.

The lateral motion devices, as before remarked, are more or less similar to the device of my Patent 1,946,893. but whereas the device of said patent is chiefly designed for constructions where the journal housing has lateral movemeritv from normal position in an inward direction only, the present device, as already remarked, is especially designed'for constructions wherethe Journal housing is provided for later- 4 al movement from normal positionin both outward and inward directions. Accordingly in the construction of the patent the outer ends of the end portions of the device are-disposed opposite the inner walls of their adjacent journaL housportion of the device against the resistance of ings, the journal housing at the end of the device where the shock emanates operating, when moved by the shock, to move the adjacent end the resistance means of the device, while the opposite end portion by its engagement with its adjacent journal housing, which housing normally bears against its adjacent side frame member, is simultaneously stopped against movement and a cushioning effect thus produced. In the device of the present construction the end portion is stopped against movement by its outer end contacting with its adjacentside 'by a shock or blow emanating from the wheel 45 and that the effect of the shock or blow has been spent, leaving the devices free to function as centering devices. First it should be noteti that inarriving at these positions the assemblage involving the journal housing 9 has been in eflect pulled along by the opposite assemblage through the functioning of the rigidly connected housing II. In the centering of the parts the operation -is reversed. The end 33 of the end portion 3|,

due to the compression of the resistance means, maintains its contact with its adjacent side "frame member 3, and the part or shoulder 36 which is in pressed engagement with the abutment or lug 25 moves this abutment or lug and the housing 9 which it forms a part of, toward its side frame member 4 to normal position due I to the recoiling of the compressed springs forming the resistance means. The housing II and journal housing 8 are pulled along, so to speak, with the housing 9, to normal positions. The shoulder l9 forces the race l4, and the race [4, due tothe direction of angularity of its bearing surface and that of the race I 3,,forces the race I3 and series of rollers l5 to normal positions. The race l3 bears against the ring I 8 and the V ring 18 bears against the collar I1, thereby forcing the axle I to normal position. The axle I and the several parts of the frictionless bearing it are therebymoved to normal positions by pushing rather than pulling forces. The collar I'l bearing against the ring l8, and the ring I 8" bearingagainst the race l3, eflect a simultaneous pushing of the race l3 to normal position, and the race l3, due to the direction of angularity of its bearing surface and that of the race l4, efiects, by pushing actions, a movement of the series of rollers l5 and race I4 simultaneously to their respective normal positions. It will be understood that both of the devices operate simultaneousl in the same manner, and also that the various parts function in a corresponding manner to effect the restoring of the 40 parts to their normal positions when the blow or shock emanates from the wheel 44. The parts adjacent the side frame member 3, during such centering operation, function similarly to the parts adjacenttthe side frame member 4, and

vice versa, as just described when the blow or shock emanated from the wheel 45, and a more detailed description is not deemed necessary; Coming now to the exempliflcation of the invention shown in Figs. 4 to 6:In the main this embodiment is quite similar to the embodiment shown in Figs. 1 to 3 except that a different style of frictionless bearing is employed, the housing Ll eliminated, and other means,

which function in part similar to the housing I I,

substituted therefor, all of which will presently more fully appear.

Various of the parts similar to those of Figs. 1 to 3 are indicated with similar reference characters with the letter a. aflixed. The type of frictionless bearing here employed is known as the SKF roller bearing and is shown in the patent to Tawresey, 1,787,459, January 6, 1931, to which patent reference may be had for afuller understanding thereof. Lateral motion resistance and centering devices are employedsimilar to those shown in Figs. 1 to 3 and similarly located.

The frictionless bearing Ila of-the housing 811 comprises an inner race 13a, an outer race a and two series of rollers l5a connected by a cage (not sh0wn),in the usual manner. A spherical bearing surface for the two series of rollers is provided on one of the races, in the'present instance the race Ila. This spherical surface posi- 76 at the center of the race l3a areshoulders i611 thereby confining the'rollers of the series against endwise movement relative to the race i3a but 10. permitting angular tilting movement thereof relative to the race [4a.

It will be understood that there is the usual slight amount of play between the various parts which in cooperation with the spherical bearing surface permits, when occasion arises, a slight free angular or tilting relative movement between the axle la with its race lid. and the housing to. with its race Ma. If provision were not present for such slight free relative tilting movement an undesirable tendency to twisting of various of the parts with attendant undue pressure thereof 'destroyingto some extent thefree frictionless functioning of the bearing, would result.

The housing ll of the previousconstruction,

as before remarked, is not present in this construction and other means are providedwhich function in part similar to the housing ii. Such means in the present instance comprises aspreader 46, which has the general shape of a 0 channel, open at the front, in which the lateral motion resistance device is. housed. The ,back

wall of the spreader is vertical and the top and bottom walls are horizontal. The spreader is M provided, at its end adjacent the abutment or lug 24a, and oppositely disposed to the inner face thereof, with an end wall 41. connected to the back, top and bottom walls of the spreader, havpasses through these passageways with the part or shoulder a disposedi opposite the inner face 50 of the end wall 411. The spreader- 46 is thus mounted upon the lateral motion resistance device 30a and is prevented from outward movement by the engagement of the end .portion Ma of the device with the rear face of the passage- 55 way formed in the end wall 41.

Lugs 48, provided withoutwardlyfacing shoulders 49 are formed on the inner face of the iournal housing 8a; one, above and one below' the end wall 41, preferably positioned near the top 6 and bottom respectively of the journal housing. j Extensions 5|] are formed on the end wall 4'|,-one

protruding upwardly with its upper portion disposed in the angle formed by the shoulder of the upper lug 48 and one protruding downwardly with its lower portion disposed in the angle formed'by the shoulder of the lower lug 48.

The rear faces .of these upper and lower porticns of the extensions are disposed. opposite thejront faces of the shoulders 49, thereby hold- 70 ting the spreader from moving toward the axle la.

The outer.side faces of these upper and'lower portions of the extensions are disposed opposite the inner faces of the lugs 48, thereby preventing eitherof the ioumal housings from movin 75 toward the other from their normal positions to lessen the distance therebetween. The spreader is thus held by its engagement with the shouldered lugs 48, the lateral resistance device 3041 and the abutments or lugs 24a, from displatement in any direction. 5 The parts at the opposite side of the vehicle corresponding to the parts just described are similar, that is to say the vehicle, in this respect, is symmetrical on each side of its longitudinal center line and the construction of these parts is duplicated by a second spreader 'and associated parts on the oppositeside of the axle id, and a further detailed description of these parts is therefore deemed not necessary.

The wear surfaces between the outer ends of the end portions did and, 32a and their respective adjacent side frame members are preferably lubricated in the following er:A pipe fitting ti is secured to a cross member 52 of the frame and is provided with an inlet orifice 53 which is connected to any suitable, lubricant source of supply (not shown). The fitting is provided with four outlet branch pipes 54 which extend at their lower ends through holes in the upper walls of the respective spreaders and terminate in holes formed in the respective end. portions of the lateral motion resistance devices. The branch pipes M are su fliciently flexible and the holes in the spreaders are made sufliciently large'to provide for the limited relative lateral movements allowed the end portions of the lateral motion resistance devices. Each *of the end portions of the devices is provided with a passageway ht extending from and communicatingwith therespective pipe M te the outer end of l the respective end portions. Thus a lubricant may be conveyed from the lubricant source of supply to the-said wear surfaces. 'While" this lubricating means is shown only in connection with the construction of'Figs. 4 to 6, it is obvious that in a suitable manner it may, when desired,

he added to the construction of Figs.,1 to 3.

The operation of the device is as follows:

It will first be noted that the spreaders it are not rigidly connected to the journal housings. They merely lie with their end walls opposite the adjacent abutments or lugs forming part of the housings, forming thereby, in sheet flexible connections with the housings, leaving the housings free for any slight relative angular or tiltingmovements with the axle as has been previously mentioned. While such connections prevent the housings from moving closer together they do not prevent them from moving further apart.

This latter possible movement is prevented in the following mamierz-The outer races are disposed in the housings between shoulders formed in the housings thereby preventing any lateral movement between the outer races and their ad- .jacent housings. The inner races are.disposed'60 between rings 56 mounted on theaxle with their outer ends adjacentthe respective wheels and their inner ends adjacent the inner 'races, and rings 51 mounted on the axle with their outer ends adjacent the respective collars 58 formed 65.

move the housingflinearerto its-adjacent wheel the series of rollers most remote from the wheel would prevent such movement, and should the tendency for movement be in the opp site direction the other series of rollers would prevent this. Therefore the several parts of each assemblage will maintain their normal aligned positions at all times, bearing in mind however that the slight relative angular or tiltingmovements, already referred to, may take place under certain conditions of service.

When the axle tilts, as when one wheel is passing over a higher section of track than the opposite wheel, the assemblages tilt likewise therewith, the frame-flanges of the journal housings being suitably flared on their inner faces from their central portions upwardly anddownwardly in the usual manner to facilitate such tilting-p .The simultaneous tilting of the two journal housings and their respective attendant outer races is effected or assured by the spreaders 46, due to their engagements with the housings, which engagements, for attaining the best results, are, as aforedescribed, at widely spaced points of the respective journ'al housings. These spreaders provide for an easy tilting of the assemblages at such times and prevent any twisting action that would occur between the parts of the frictionless bearings which would lessen to a corresponding extent their, desired frictionless functioning were the spreaders not emoloyed.

Coming now to the operation" of the axle and its associated parts when subjected to a blow or shock, as for instance a blow or shock emanating from the wheel 45a, the lateral motion resistance device functions similarly to that of Figs. 1 to 3 and a repetition of its detailed operation will therefore be unnecessary here. The relative movements of the other parts involving the assemblages are however difl'erent.

The axle moves laterally in the direction of the blow or shock, that is to say toward the side frame member 3a, carrying the inner race adjacent the wheel 450 with it. The corresponding present construction with that of Figs. 1 to 3 it will be noted that there is quite a difference therebetween. During this movement of the parts the resistance means is compressed similarly to that of Figs. 1 to 3 and the effect of the shock or blow thereby cushioned. Both of the taneously in a similar manner. It is believed that from the 'aforegoing description the operation of the parts will be obvilateral motion resistance devices operate simulous when the shock or blow emanates from the wheel a. Likewise the centering operation of the device whereby the various parts arebrought to their normal positions is believed to be ob- 'vious and no further detailed descriptions of at each side thereof, an axle; a wheel on each The oppo- .c'ent thereto to be stopped by engagement therethe art that many and various, changes and modifications may be made thereto, but it will be understood that all such changes and modifications as fall fairly within the spirit of the present invention and the scope of the appended 5 claims are contemplated as a part of this invention.
